If you're handy, you can even just buy an NTC thermistor with the correct value for very little at an electronics store, and pot it yourself with f.i. some sillicone kit
I believe standard value required is 10 kOhm

I wouldn't go that route unless strictly necessary, after all I can afford the mirror assembly. But, if it happens again I might just do what you are suggesting.random example

I just saw the links, those are the right ones. The same used on a Jeep Renegade, Fiat 500X,RAM, and other FCA vehicles.random example

Thanks All - So I bought a new sensor and fitted it (not a particular hard job), and I'm assuming its a standard 10k thermistor. It had the right number - 71753245 - here was the link - New Sensor, exterior temperature, 71753245 60779278 06445F9 6445.JS 6445.F9 | eBay
My temperature now is showing at 50'C (it does work though from putting it in ice it drops 10'C and then warms up ok).
Does it need calibrating though? As obviously at the moment its about 40'c out?
Any thoughts?
Thanks
Matt

I see that one has like a clip in the front for a screw or to clip to a post. I have seen others that don't have that clip. Can you take a picture of the original one? The one you replaced? Thanks

specially as it is not a rare happening for the sensor to fail

Alfa is trying to make money off of service.
They sell it as part of the whole unit BECAUSE it doesn't break often, as such it isn't profitable to stock inexpensive parts that don't sell in high volume, but is it profitable to sell expensive parts that don't sell in high volume.
Especially in the US now because... Somehow... Even with all the "shortages"... The warehouses are full... Not sure how that works. Seems fishy, but regardless,. Most of the warehouse in CA are close to full and the rest of the US isn't much better. That part I'm pretty positive of.
(In auto parts warehousing, IMO the problem is too much old stock, there are billions of parts for cars that don't really get driven anymore sitting on shelves, stuff for discontinued cars that never sold or models that have aged out of the fleet for instance. If you have ever gone searching for a part in a 30 year old warehouse in the middle of Az... you know all about stumbling on an entire shelving unit filled with Geo Metro parts, the boxes literally decomposing on the shelf.)

Don't know it's like this so badly in the US and not there, but maybe parts of Europe have more warehouse space and/or better costing for storage so they stock the part in a more inexpensive form. That's a guess as to why the part is available by itself in some markets there for Alfa but not here.
Could also just be as simple as... There's more Alfa's in Europe and the dealers in those areas have a larger pool of old cars to fix and profit off so they don't need to manipulate pricing to create profits because they have work. Guessing, but that probably makes the most sense in an armchair analysis. That would also explain why for other makes the part is available in the US, those makes also have a larger used car fleet and more work of dealer service depts then Alfa. Sorry for the rambling...it's how I think while typing....
Also not disagreeing about it being rubbish. Absolutely is, the reasoning no matter how you cut it is rubbish. Just attempting to explain some how it "makes sense" so maybe the situation won't be so annoying.

America's biggest warehouse is running out of room. It's about to get worse
America's largest warehouse market is full as major U.S. retailers warn of slowing sales of the clothing, electronics, furniture and other goods that have packed the distribution centers east of Los Angeles.

Got the same problem on my 2018 Stelvio TI (Canada).
What is the exact part number for that bloody sensor I must get?
My dealer told me it will cost me $1355 plus labor to replace that side mirror.

Ambient Temperature Sensor Failure = Solution?
Hi, I know this has been discussed int he past, but I have not found a solution to the problem, so maybe someone knows the answer or can steer me in the right direction. I have a 2018 Stelvio 2.0L and two days ago the A/C wouldn't cool propertly. I noticed that the ambient temp reading was 45F...

Be careful, from what I understand this is not the one. This one has a tab/clip for a screw. This type has a different Ohm rating and will read differente. Read further above for the right one, it was posted by someone else. I will post anyways.

Otto, this is the correct one: Brand New - Fiat 500 C X L Outside Temperature/Ambient Sensor Underneath Mirror | eBay
*This one does not have the clip. It is P/N ABHN - T18. For reference purposes it's OEM: 735603615 and 735655747
